Ingredients

PEANUT BUTTER COOKIE LAYER

  • 2 cups (516g) creamy peanut butter
  • 2 cups (400g) granulated sugar
  • 2 large eggs, room temperature
  • 1 tablespoon McCormick Vanilla Extract

OREO LAYER

  • 24 Oreo cookies, double stuffed

BROWNIE LAYER

  • 1 box (18.4 ounces) brownie mix, prepared per box instructions
  • ½ teaspoon McCormick Cinnamon

PEANUT BUTTER SAUCE - OPTIONAL

  • ½ cup (129g) peanut butter, chunky
  • ½ cup (1 stick or 113g) butter
  • ½ cup (85g) butterscotch chips

Instructions

PEANUT BUTTER SLUTTY BROWNIES

  • Preheat oven to 350°F.
  • In a bowl of a stand mixer (or a large bowl if using a handheld mixer), cream together the peanut butter and sugar until well blended.
  • Beat in the eggs and vanilla.
  • Press the peanut butter cookie mixture into a greased 9x13-inch pan.
  • Place the Oreo cookies on top of the peanut butter cookie layer. (No need to crush them or break them into pieces.)
  • In a separate bowl, make the brownie batter by following package instructions.
  • Add cinnamon to the brownie batter. (Don't skip this! It's SO good!)
  • Pour the brownie batter over the layer of Oreo cookies.
  • Bake for 35-40 minutes, or until an inserted toothpick (in the brownie layer only) comes out with a few crumbs, but not wet batter.
  • Allow to cool for 10 minutes before cutting and adding the optional Peanut Butter Sauce.

PEANUT BUTTER SAUCE - OPTIONAL

  • In a medium saucepan, melt butter and peanut butter over medium-low heat. Once they are fully melted and combined, add in butterscotch chips. Remove from heat and stir continually until mostly melted.
  • There will be chunks in the bottom of the pan, but this is okay. Set aside to cool slightly. Pour over the brownies as an added bonus!
